The Handbook

On no occasion call yourself a philosopher, and do not speak much among the uninstructed about theorems (philosophical rules, precepts): but do that which follows from them. For example at a banquet do not say how a man ought to eat, but eat as you ought to eat. For remember that in this way Socrates[*](See iii. 23, 22; iv. 8, 2.) also altogether avoided ostentation: persons used to come to him and ask to be recommended by him to philosophers, and he used to take them to philosophers: so easily did he submit to being overlooked. Accordingly if any conversation should arise among uninstructed persons about any theorem, generally be silent; for there is great danger that you will immediately vomit up what you have not digested. And when a man shall say to you, that you know nothing, and you are not vexed, then be sure that you have begun the work (of philosophy). For even sheep do not vomit up

their grass and show to the shepherds how much they have eaten; but when they have internally digested the pasture, they produce externally wool and milk. Do you also show not your theorems to the uninstructed, but show the acts which come from their digestion.
